The client
A self-employed general contractor in Vernon, sole proprietor, running two lines of work under one T2125: renovation contracts for other homeowners, and the occasional buy-renovate-resell project on his own account. He wanted to refinance his own home to fund the acquisition and materials budget for his next project.

The problem
The flip that produced the $96,000 was ordinary to him: buy a dated house, renovate it, sell it, move to the next one. He'd done it three times in four years, always inside a single T2125. To the first underwriter who opened the file, a six-figure jump in one year's business income, sourced to a single property sale, looked like exactly the kind of one-time capital transaction self-employed underwriting guidelines exist to strip back out before averaging — a windfall, not a repeatable income stream.
That would once have required a real argument. Before 2023, whether proceeds from a quick resale were a capital gain or business income turned on an adventure or concern in the nature of trade analysis — intention at purchase, frequency of transactions, nature of the property, all weighed as facts, usually needing an accountant's letter to settle. Parliament removed that argument for housing.
What the flipped-property rule actually does
- ▸Subsection 12(12) — where a taxpayer would have a gain on disposing of a flipped property, the taxpayer is deemed to carry on a business, the property is deemed inventory, and the gain is fully taxable business income, not a capital gain
- ▸Subsection 12(13) — a flipped property is a Canadian housing unit owned less than 365 consecutive days before disposition, subject to a short list of life-event exceptions (death, relationship breakdown, job loss and similar) that plainly did not apply here
- ▸Subsection 12(14) — a loss on a flipped property is deemed nil, which cuts the other way but confirms the same point: the statute decides the character, not the taxpayer's stated intention
The renovation had run 210 days start to sale — well inside the 365-day line, and none of the listed exceptions applied. That made the outcome automatic: the $96,000 was business income by operation of the Act the moment the sale closed, reported on the same T2125 line as his contracting income rather than on Schedule 3. No underwriting exception or accountant's opinion letter was needed to establish that; the section did the work.
The numbers
This is a conventional refinance to 70.8% loan-to-value, so 39%/44% are not an insurer's ceiling here — the file was sized against the lender's own policy, with plenty of room once the flip profit was correctly counted.
| The refinance | Amount |
|---|---|
| Appraised value | $650,000 |
| Existing mortgage balance | $310,000 |
| Cash released for the next project | +$150,000 |
| New mortgage | $460,000 |
| Two years of business income | Figure |
|---|---|
| Year 1 — contracting only | $71,000 |
| Year 2 — contracting ($71,000) + flip profit ($96,000) | $167,000 |
| Two-year total, divided by 24 months | $9,917/mo |
What the flip profit was
| The resale that funded it | Figure |
|---|---|
| Purchase price | $298,000 |
| Renovation cost | $54,000 |
| Resale price, 210 days later | $460,000 |
| Profit, deemed business income under §12(12) | $96,000 |
Sizing and ratios
| Refinance sizing | Figure |
|---|---|
| Loan-to-value ($460,000 ÷ $650,000) | 70.8% |
| Contract rate, 5-year fixed (illustrative, not a quote) | 5.29% |
| Minimum qualifying rate — greater of contract + 2% and 5.25% | 7.29% |
| Monthly payment at the qualifying rate | $3,305 |
| Ratios on $9,917/month | Figure |
|---|---|
| Housing costs (qualifying payment + $300 tax + $150 heat) | $3,755 |
| GDS ÷ $9,917 | 37.9% |
| TDS (housing + $380 vehicle loan) ÷ $9,917 | 41.7% |
Strip the flip profit back out, the way the first read of the file did, and the two-year average falls to $5,917/month — TDS climbs past 60% and the refinance does not work. Counted correctly, under a rule the self-employed underwriting guidelines did not anticipate needing to argue about, it was the strongest year in his three-year history.
The solution
A BC-licensed submortgage broker treated the flipped-property rule as settled law rather than a negotiating position, and built the file around what the statute already decided.
First, confirmed the holding period against the closing statements on both ends. Purchase to sale was 210 days — inside the 365-day line in §12(13) with room to spare, and none of the exception grounds (death, marriage breakdown, job loss and the rest of the short list) applied, so there was no route out of the deeming rule and no need to look for one.
Second, matched the T2125 to the deeming rule's own mechanics. Because §12(12) deems the property to be inventory rather than capital property, the profit belonged on the business-income line, not Schedule 3 — which is exactly where his accountant had already reported it. The underwriter's first read had been trying to move a figure that was never on the capital-gains side of the return to begin with.
Third, showed the pattern wasn't a one-off. Two prior resales, both inside a year of purchase, both reported the same way, supported treating this as a repeatable second line of the same business rather than an unrepeatable windfall — consistent with how the two-year average is meant to work.
The outcome
The refinance funded at $460,000, 70.8% loan-to-value, on a five-year fixed at 5.29%, qualifying payment $3,305, GDS 37.9% and TDS 41.7%. The $150,000 released went straight to the acquisition and renovation budget for his next project.
This is a conventional (uninsured) refinance, so CMHC's ratio ceilings do not bind directly; 39%/44% are shown as the lender's own applied policy, not an insurer's rule.
What to take from this file
- 01Since 2023, a housing unit held under 365 days is deemed business income by statute. Subsections 12(12)-(13) of the Income Tax Act removed the old adventure-in-the-nature-of-trade analysis for housing — the holding period and the short exception list decide it, not the taxpayer's stated intention.
- 02Check where the figure actually sits on the return before arguing about it. A deemed-business-income gain belongs on the T2125, not Schedule 3 — if the accountant already reported it that way, there is nothing to reclassify.
- 03A self-employed borrower can run more than one income stream through the same business. Contracting income and flip profit on the same T2125 are both business income; averaging them together is not a workaround, it is the correct read.
- 04Confirm the exceptions before relying on the deeming rule. Section 12(13)(b) carves out disposals driven by death, relationship breakdown, job loss and a short list of similar events — check the closing dates against them rather than assuming the general rule applies.
